Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Saunders, 1961

Comment (Workings): Workings / Exploration = Surface sampling only.

Comment (Deposit): Model Name = Cyprus massive sulfide (Cox and Singer, 1986; model 24a)

Comment (Geology): Geologic Description = The area of this occurrence is underlain by a 2,00-meter-thick sequence of Lower Permian? and Pennsylvanian, massive volcanic flows, breccias, and subordinate volcaniclastic rocks, all largely andesitic in composition (Wilson and others, 1998). The occurrence consists of pyrite and chalcopyrite disseminated in the volcanic rocks.

Comment (Geology): Age = the sulfide minerals probably are syngenetic with their Lower Permian and Pennsylvanian host rocks.
